Post-socialist “illiberal democracies”: do de jure constitutional rights matter?

Are de jure constitutional rules significant for constitutional practice? We pose this question with regard to de jure and de facto protection of constitutional rights in post-socialist countries of Europe and Asia. While, after 1989, these countries enacted broad catalogues of rights and freedoms, they are by now often regarded as electoral, not liberal democracies, i.e. they generally allow for political competition and fair elections but witness considerable violations in civil and minority rights. We use various econometric techniques to determine whether, and under what conditions, de jure rights originating from texts of post-socialist constitutions matter for de facto protection of rights in these countries. Our results reveal no such significant unconditional effect, with the exception of freedom of assembly/association. We do, however, find a positive significant effect conditional on judicial independence, democratization level, and robustness of civil society. The conclusions allow to propose guidelines for post-socialist legislators and bring a contribution to the broader debate on the role of de jure constitutional rules for their de facto equivalents, which has so far been essentially inconclusive.


Introduction
Economic literature interested in constitutions and constitutional change systematically confirms the significance of constitutional frameworks for policy decisions and various economic outcomes (see surveys by Voigt 2011Voigt , 2020a. However, 1 3 these studies seldom focus on constitutional provisions as they have been formally laid down in constitution texts (i.e. de jure constitutions) but rather on the actual functioning of constitutional rules-the so-called de facto constitutions. In fact, the conclusions of a handful of studies pertaining to the direct economic relevance of formal constitutional rules are, at best, ambiguous (e.g. Bjoernskov 2015-referring to property rights protection; Metelska-Szaniawska 2016; Gutmann and Voigt 2018-with reference to constitutional court, and more generally, judicial independence; Chilton and Versteeg 2017;Bjoernskov and Mchangama 2019-with regard to de jure protection of social rights). Recently, the discrepancy between de jure and de facto constitutions also became the focus of studies in this field, relating in particular to the so-called constitutional underperformance (Law and Versteeg 2013) or de jure-de facto constitutional gap (Metelska-Szaniawska 2020; Voigt 2020b). If, based on these studies, one aims at formulating recommendations with regard to desired constitutional change, the crucial question concerns whether and, if so then to what extent, the text of the constitution actually impacts constitutional practice. If such impact is confirmed, one can speak of indirect relevance of de jure constitutions for policy decisions and economic outcomes, even if, as argued above, their direct effects may be questionable. In this paper we pose such question with regard to the protection of civil rights in post-socialist countries of Europe and Asia, 1 i.e. we aim to determine whether, and under what conditions, de jure rights originating from texts of post-socialist constitutions matter for de facto protection of rights in these countries. Pre-1989 communist (or socialist) constitutions constituted typical examples of window-dressing (e.g. Sakwa 1993; Ludwikowski 1996), resulting in particularly large gaps between de jure and de facto protection of various categories of rights and freedoms. The fall of communism in Central and Eastern Europe in 1989, and later in former Soviet republics, as well as the transition of their political systems towards democracy that followed, marked an important contribution to the socalled third wave of democratization (Huntington 1991). These events can also be regarded as a certain turning point in history, since which more countries in the world qualify as democracies than non-democracies (Marshall et al. 2014). To allow for systemic changes that occurred after 1989, these states faced the need to introduce new constitutional frameworks. In fact, the adoption of post-socialist constitutions took place in the period 1990-2011, with greatest intensity between 1990 and 1996. 2 Breaking with their pre-1989 past, these constitutions generally envisaged 1 These are: countries of Central and Eastern Europe (Albania, Bulgaria, Czech Republic, Hungary, Poland, Romania, Slovakia); former Yugoslavian republics (Bosnia and Herzegovina, Croatia, Montenegro, North Macedonia, Serbia, Slovenia); and former Soviet republics (Armenia, Azerbaijan, Belarus, Estonia, Georgia, Kazakhstan, Kyrgyzstan, Latvia, Lithuania, Moldova, Russia, Tajikistan, Turkmenistan, Ukraine, Uzbekistan). 2 All countries except Hungary and Latvia introduced at least a provisional constitution in this period. Hungary operated on the basis of its numerously amended 1949 constitution throughout most of transition, adopting a new constitution as late as in 2011. Latvia returned in 1991 to its 1922 constitution (with significant amendments). This unprecedented time of broad-scale constitutional change has sometimes been called a "gigantic natural experiment" (Elster 1993, p. 449). broad, unambiguously worded catalogues of rights and freedoms that are directly enforceable and binding upon all state institutions and ensured their supremacy over legislation by a system of judicial (constitutional) review (Sadurski 2002). Nevertheless, more and more often recent political economy literature raises the point that democracies, which developed in post-socialist countries of Europe and Asia are, in fact, electoral not liberal democracies, i.e. they allow for political competition and, in principle, fair elections but witness considerable violations in civil rights of various minorities and groups which are not in power (Mukand and Rodrik 2020). Our earlier studies of the de jure-de facto constitutional gap in the area of rights and freedoms for this group of countries also confirm that, except for a handful of results for Estonia and Moldova in the very first years of transition, all post-socialist states demonstrate positive de jure-de facto gaps, indicating that constitutional practice diverges from the formal rules concerning protection of rights and freedoms laid down in post-socialist constitutions (Metelska-Szaniawska 2020). This additionally motivates the question whether de jure rights originating from the texts of postsocialist constitutions matter at all for de facto protection of rights in these countries, and if so, then what the conditions for this effect are.
Protection of constitutional rights and freedoms is an area where discrepancy between de jure and de facto constitutions is particularly apparent and the relevance of constitutional text for constitutional practice has already received some attention (see e.g. Davenport 1996;Keith 2002Keith , 2012Keith et al. 2009;Fox and Flores 2009). Most of these studies suggest that structural provisions, such as e.g. judicial independence, are more effective in constraining governments than de jure rights and freedoms, regarded as not much more than merely parchment barriers. More recent studies reveal, however, several limitations and caveats of these early approaches and bring forward evidence of at least partial or conditional relevance of de jure constitutional rights provisions for de facto protection of these rights. Melton (2013) suggests, for example, that while entrenching freedom of religion, freedom of the press, and the prohibition of torture in the constitution does not improve the likelihood of observing that right/freedom in practice (in fact, in certain situations, entrenchment might increase the violation of these rights/freedoms), constitutional entrenchment does significantly improve de facto protection of freedom of association, freedom of expression, and freedom of movement (under a variety of conditions, the most important of which is the functioning of an independent judiciary). Most recently, Chilton and Versteeg (2016) suggest that the effectiveness of de jure political rights depends on the type of rights in question: rights that establish organizations with the incentives and means to protect them (called "organizational rights", e.g. the right to establish a political party or to unionize) are self-enforcing and therefore more effective than rights that do not establish such organizations ("individual rights", e.g. freedom of expression, freedom of movement). Our contribution links this theoretical and empirical constitutional economics literature with recent cross-disciplinary studies on illiberal democracies, problems of rights enforcement, constitutional underperformance and the constitutional de jure-de facto gaps in post-socialist countries. The results reveal no significant unconditional effect of de jure rights originating from the texts of post-socialist constitutions for de facto protection of rights in these countries, with the exception of freedom of 1 3 assembly/association-the "most organizational" right in our sample. The data do, however, confirm significant conditional effects.
The paper is structured as follows. In Sect. 2 we provide background information on de jure and de facto protection of constitutional rights and freedoms in postsocialist countries of Europe and Asia. Section 3 reviews the relevant literatureboth theoretical and empirical. Based on this literature, in Sect. 4 we construct our empirical model aiming to test the relevance of de jure constitutional rules for their de facto equivalents and discuss the employed econometric techniques. Section 5 presents the results pertaining to direct and conditional effects, both for aggregate measures of rights protection, as well as with regard to individual rights. The paper finishes with conclusions.

Constitutional rights and freedoms in post-socialist countries
Post-socialist countries did not develop a common constitutional model and this also relates to constitutional catalogues of rights and freedoms. All currently operative post-socialist constitutions contain a separate section devoted to rights and freedoms provisions, however even with regard to such crude indication as the length of this section they vary considerably: Bosnia and Herzegovina (549 words), Latvia (965 words), and Lithuania (1233 words) place at one extreme, while Romania (4082 words), Ukraine (4192 words) and Serbia's 2006 Constitution (5580 words) on the other (Elkins et al. 2014). A special case in this respect is the Czech Republic, where rights and freedoms are encompassed by a separate document (the Charter of Fundamental Rights and Basic Freedoms) attached to the constitution.
Data gathered by Elkins et al. (2014) allow to identify 117 different constitutional rights present in constitutions of the world since 1789, 35 of which are categorized as civil and political rights, while 28 as minority rights. 3 Based on a subset of this data for post-socialist countries, in Table 1 we present a very general picture of the de jure protection of rights and freedoms in constitutions of these states, focusing, in particular, on civil and political rights, as well as minority rights. 4 Overall, postsocialist countries constitutionalize on average ca. 50 rights, with the constitutions of Serbia (69 rights) and Armenia (67 rights) being most protective in this respect and constitutions of Bosnia and Herzegovina (25 rights) and Latvia (32 rights) on the other extreme. The variation between constitutions, as measured roughly by the Post-socialist "illiberal democracies": do de jure… Table 1 De jure protection of rights and freedoms in post-socialist constitutions (as of 2013). Source: Own elaboration on the basis of Elkins et al. (2014) For countries, for which data for 2013 were not available, the most recent year is taken into account and reported in brackets next to the country name 1 3 standard deviation, is noticeable (8.5), however drops below 4 when one removes the 4 extreme cases mentioned above from the sample. The smallest variation is encountered for the category of our interest in this paper-i.e. political rights and civil liberties, where nearly all countries score between 14 and 19 (mean = 16.7, standard deviation = 1.7), with the sole exception of Bosnia and Herzegovina, which protects 12 such rights in the constitution. More differences are observed for the remaining categories (the largest ones-for social and economic rights). Minority rights (mean = 7.5, standard deviation = 2.8), together with anti-discrimination measures contained by the discussed constitutions, are most pronounced for such countries as Armenia (12 rights), Serbia and Slovakia (11 rights), while in a few other constitutions they are hardly mentioned-Belarus (2 rights), Poland (1 right), Kyrgyzstan (0). The practical operation of provisions regarding constitutional rights differs more significantly amongst the discussed countries. Information about de facto protection of rights and freedoms is available from several databases, in particular the CIRI Human Rights Data Project (Cingranelli et al. 2014) and Freedom House's Freedom in the World and Freedom of the Press rankings (Freedom House 2017, 2019). The CIRI database contains quantitative information on government respect for 15 internationally recognized human rights for 202 countries, annually from 1981 to 2011. They include: (1) physical integrity rights with data on disappearances, extrajudicial killings, political imprisonment, and torture; (3) empowerment rights, such as freedom of assembly and association, freedom of domestic movement, freedom of foreign movement, freedom of speech, electoral self-determination, freedom of religion, and workers' rights; as well as (3) women's economic, social and political rights. 5 Post-socialist countries generally place in the middle of the global CIRI rankings. Table 8 in the Appendix reveals aggregate scores for each category of rights included in this database-personal integrity rights (PIR), empowerment rights (EMPR), and women's rights (WR)-for all post-socialist countries (and the overall post-socialist averages) for the years 1981, 1990, 2000, and 2011 (the last year for which it is available). For the sake of clarity we normalize the obtained indicators to take values from the interval [0,1] with higher values corresponding to more respect for rights. The remaining columns of Table 8 present post-socialist countries' scores on Freedom House's political rights (PR), civil liberties (CL), and freedom of the press (FP) indicators for similar moments in time as well as in the last year for which this data (on the FP indicator, specifically) are available-2017 (normalized according to the same procedure as above 6 ). The political rights ranking Post-socialist "illiberal democracies": do de jure… is based on a checklist including the electoral process, political pluralism and participation; the civil liberties indicator encompasses freedom of expression and belief, associational and organizational rights, the rule of law, personal autonomy, and individual rights; while freedom of the press indicator relates to three components-the legal environment, the degree of political influence in the content of news media, and the economic environment for the media. All measures presented in Table 8 generally exhibit considerable increases since 1980/1981, however: this is certainly not a constantly upward trend (in particular, indicators for political rights and civil liberties drop in 2017); there are considerable differences between categories of rights and among countries; and, most visibly, the scores for all categories of rights, generally significantly different from 1, demonstrate noticeable disrespect for rights and freedoms in the post-socialist countries during the included period.
In an earlier study focusing on the size and evolution of the gap between de jure and de facto protection of a selection of civil and political (constitutional) rights in post-socialist countries (Metelska-Szaniawska 2020) 7 we revealed that the gap takes highest values for Russia, Uzbekistan, Tajikistan and Azerbaijan. Countries such as Armenia, Kyrgyzstan, Belarus, and Turkmenistan follow with a generally increasing trend (they experience a larger gap recently than they did at the outset of transition). Serbia demonstrates highest values of the gap for early years of transition, however experiences a considerable decrease (by half) later, what is likely to be explained by the turbulent history in the area during the 1990's. Countries with relatively lowest values of the gap are Estonia, Slovenia, Bosnia and Herzegovina (since 2005), as well as Moldova (however, the latter with an increasing trend).
In a different approach to this topic, Law and Versteeg (2013) propose a measure of constitutional underperformance revealing the extent to which countries promising a relatively broad catalogue of rights de jure in their constitutions succeed at upholding those rights in practice. Each country's underperformance score provides the proportion of the total number of rights in its constitution that was actually respected, i.e. 0 indicates that the country seriously violated all of the rights included its constitution, while 1 indicates perfect respect of all the rights included in the constitution. Table 2 presents a subset of this data for post-socialist countries of Europe and Asia in the area of personal integrity rights, civil and political freedoms, socio-economic and group rights, as well as their overall scores. 8

The data presented in Table 2 allow to determine the types of post-socialist constitutions with regard to protection of rights and freedoms and, in particular, to distinguish between countries with strong constitutions and those with sham constitutions. 9 Specifically, of the 26 post-socialist constitutions for which data are available 10 18 are strong constitutions, while 6 are sham constitutions. Countries with the highest underperformance scores (i.e. most respect for rights in their constitutions) are Slovenia (#3 'strongest' constitution of the world according to Law and Versteeg 2013 11 ), the Czech Republic (#4 in the above classification) and Estonia. On the other extreme one will find Russia (#5 'worst sham' constitution in the world according to Law and Versteeg 2013), as well as the remaining post-socialist countries with sham constitutions-Uzbekistan, Tajikistan, Turkmenistan, Belarus, and Azerbaijan. It is noticeable that most 'disrespect' for the constitution is found in the area of civil and political freedoms, where countries with sham constitutions such as Russia, Uzbekistan and Turkmenistan score 0. 12 To sum up, de jure catalogues of constitutional rights are relatively well-developed in post-socialist countries and they do not vary greatly between these states. Differences are the smallest in the area of political and civil rights and the most noticeable for minority rights. De facto protection of constitutional rights, in turn, varies most in post-socialist countries in the area of political and civil rights, therefore, determinants of this divergence constitute the subject of further considerations in this paper.

Literature review
Given the main focus of this paper, i.e. determining whether de jure protection of constitutional (civil) rights impacted constitutional practice in this area in postsocialist countries of Europe and Asia, in this section we present, in a nutshell, the theoretical background for analysis of relationships between de jure and de facto Table 2 Constitutional underperformance in post-socialist constitutions. Source: Own elaboration on the basis of Law and Versteeg (2013, appendix II) GP gross number of rights promised in the constitution, NP net number of rights promised for which de facto performance data is available, FU number of rights in the constitution that were fully upheld, PU number of rights in the constitution that were partially upheld constitutional rules and review the empirical literature that has recently developed with regard to this question. We also reflect on the relevant peculiarities of postsocialist countries' constitutional framework.

Theoretical background
Laws constitute a normative system, usually constructed by legislators in order to develop social interactions (Chauvin et al. 2011). Without respect for the law, the entire social system does not work properly, failing to protect universal values and needs. The problem of respecting the law is inevitably linked with the sphere of validity of legal regulations. In this paper, we undertake a realistic approach and treat the law as valid when a significant share of legal norms' addressees behave in line with these norms (Chauvin et al. 2011). In other words, the law is valid when it is regularly applied and respected.
Interrelations between de jure and de facto rules or institutions constitute a rather recent topic in economic literature. A connected problem that has already been thoroughly studied is that of interrelations between formal and informal rules/institutions (or, put differently, between the law and social norms). 13 A de jure institution is a state of affairs that is in accordance with the law, while a de facto institution is a state of affairs which is true in fact, but does not have to be officially sanctioned (Lewkowicz and Metelska-Szaniawska 2016). Therefore, de jure institutions are a subclass of formal institutions and are external in nature (in exceptional cases external and internal simultaneously), while de facto institutions could be both informal or formal and both internal or external, provided that they are operative. 14 Identifying de facto institutions may be troublesome and, to a certain degree, discretional, as it is often impossible to mark the precise point distinguishing operative and nonoperative institutions. De jure institutions, that are not enforced and not observed, cannot be classified as de facto institutions.
There exist different types and structures of interactions between de jure and de facto institutions. De facto and de jure institutions boost each other when they lead to commonly desired behavior, while they inhibit each other when they create incentives leading to different/contrary decisions (Lewkowicz and 13 According to much of this literature, it is not possible to understand the functioning of the law without reference to social norms, which interact with the legal system (e.g. Posner 1997). The following possible relations have been discussed: (1) formal and informal rules are complements (e.g. Baker et al. 1994;Lazzarini et al. 2004); (2) formal rules are substitutes for social norms and it is possible for societies to function based on informal rules, without the need to establish costly de jure rules (Macaulay 1963;Ellickson 1991;Huang and Wu 1994); (3) formal rules are substitutes for informal rules and introduction of the former undermines or even destroys the functioning of social norms (e.g. Frey and Oberholzer-Gee 1997;Fehr and Gachter 2001); (4) depending on the particular context and conditions, formal and informal rules are complements or substitutes (e.g. Posner 2000;Zasu 2007). 14 We refer here to the internal/external classification as proposed by Voigt (2013), i.e. based on the underlying enforcement mechanism (when sanctioning is privately organized by members of the group or society within which a given institution functions, the institution is internal, while when sanctioning is public-it is classified as external). For more on de jure/de facto institutions versus other classifications of institutions see Lewkowicz and Metelska-Szaniawska (2016).
Post-socialist "illiberal democracies": do de jure… Metelska-Szaniawska 2016). In this paper, we are interested in a subset of such interactions, namely cases when de jure constitutional provisions impact (or not) de facto constitutional practice and this in the area of rights protection. With regard to this specific topic an important strand of (mainly) political science literature has developed, focusing on the question whether the constitution imposes significant constraints on those in power and establishes rules, according to which the political game is played within states, or accounts to no more than parchment barriers (see more in Levinson 2011). Other authors argue that constitutional solutions work provided that they are self-enforcing, i.e. it is not necessary that an external actor supervises the execution of a bargain (see e.g. Ordeshook 1992;Weingast 1997). Constitutional provisions written on paper and publicly available contribute to the constitutional self-enforcement mechanism thanks to providing a focal point, around which various actors may concentrate their enforcement efforts (Carey 2000;Elkins et al. 2009). Additionally, parchment may lead to creation of mutual expectations among political actors and it is essential for de facto functioning of institutions (Carey 2000). Constitutional provisions may, therefore, serve as underpinnings for de jure institutions at the post-constitutional level enhancing their operation in social practice. Effects of adopting constitutional provisions may, however, be only visible after a long period (Keith et al. 2009). In this perspective, writing down certain rules may contribute to their strength and binding force.
When investigating the relevance of de jure constitutional text for de facto constitutional practice in the field of respect for rights and freedoms, the issue of enforcement is of particular relevance. Economic literature pertaining to state repression, inspired by the rational choice approach, argues that governments decide to repress rights when their benefits from this option exceed the costs (Davenport 2007a). De jure rights may play a role in this calculus as long as they increase the government's expected cost of punishment for repressing rights (Melton 2013). Then, if the constitution is de facto enforced, this increases the likelihood of punishment for breaking constitutional rules, what, in turn, deters repression.
With regard to constitutional rights and freedoms several enforcement mechanisms may be at play. Firstly, there are types of rights and freedoms that have the potential to be self-enforcing. Self-enforcement mechanisms create a positive interrelationship between de jure and de facto constitutional rules (Melton 2013). This is, in particular, the case when rights involve setting up organizations, which have the incentives and adequate means to guard and protect them (Chilton and Versteeg 2016). The latter authors provide evidence that such "organizational rights" are indeed associated with increased de facto rights protection (as opposed to "individual rights" which do not have this feature of self-enforcement).
Secondly, enforcement of rights and freedoms may be guaranteed by an independent judiciary-an institutional solution to the dilemma of a strong state (Feld and Voigt 2003;Voigt et al. 2015). An independent judiciary is an actor that does not have incentives to breach the constitution and, at the same time, has sufficient power to prevent the government from transgressing the constitution. In such a setting de jure rights may also become self-enforcing as governments fearing punishment by (an independent) judiciary will refrain from transgressing the rights set forth in the constitution (Weingast 1997), rendering them de facto operative.
Finally, a third type of enforcement mechanism to be considered in our context is electoral enforcement, which might overtake the role of organizations or the judiciary (Davenport 2007a) and assure that de facto protection of constitutional rights does not diverge significantly from de jure content of constitutions in this area. This mechanism, consisting in citizens voting governments, that repress rights, out in subsequent elections, is a particular feature of democratic regimes. This is one of the reasons why the chances of de jure rights being de facto enforced are considerably higher in democratic than in autocratic systems. Democratic governments also tend to have less incentives to repress rights from the beginning (Davenport 2007b). Although a specific situation may occur when the majority of the society is willing to break the existing laws, we perceive such a situation as rare and unique, probably caused by groundless legislation or populism. Melton (2013) emphasizes that the existing literature on de facto enforcement of international human rights treaties already suggests that judicial independence and regime type are important conditions of the effectiveness of these treaties (e.g. Simmons 2009;Hafner-Burton et al. 2011). Another suggestion stemming from these works is that with regard to domestic enforcement of constitutional rights and freedoms, political conflict should also be considered. Firstly, in conflict settings the government may be transgressing the constitution to protect national security and if conflict is severe enough, this may be done by the government even if it is certain to be punished for doing so (Melton 2013). This is the reason why even in democracies, repression of de jure constitutional rights is much more likely in periods of political conflict (Davenport 2007a, b).
Given the considerations presented above, one may conclude that de jure entrenchment of constitutional rights is expected to improve constitutional practice under a certain set of conditions. De jure rights are neither a necessary, nor a sufficient condition for de facto protection of these rights. This is particularly clear when one considers countries, which respect rights de facto, even though they have not been de jure specified in their constitutions. This phenomenon has been coined constitutional overperformance (cf. Law and Versteeg 2013;Metelska-Szaniawska and Lewczuk 2018). The existence of constitutional overperformance around the globe indicates that it is possible that some factor other than the existence of de jure rights assures their de facto protection (Melton 2013). In other words, in some settings de jure rights are clearly redundant for constitutional practice.

Results of empirical studies
In part in relation to theoretical works and in part independently of such background, empirical studies of the relationship between de jure and de facto constitutional rules have recently began to develop. Quantitative studies have been conducted for broad samples, usually consisting of more than 100 countries from different continents and with considerable institutional heterogeneity both in the formal and factual dimension. For instance: Voigt (2007, 2018), as well as Melton and Ginsburg (2014), study this problem with regard to constitutional court independence; Melton et al. (2013) compare the relationship between de jure and de facto rules in two areas-the structure of power and constitutional rights; while Hayo and Voigt (2008) analyze the influence of de jure central bank independence on its factual level.
The de jure-de facto relationship in the area of constitutional rights and freedoms has also been the focus of several studies with an empirical component (see e.g. Davenport 1996;Keith 2002Keith , 2012Keith et al. 2009;Fox and Flores 2009). As already mentioned, most of these studies suggest that structural provisions are more effective in constraining governments than de jure rights and freedoms. More recent works, however, question the validity of these results on several grounds, suggest more sophisticated and rigorous empirical techniques, and bring forward evidence of at least partial or conditional relevance of de jure provisions for de facto protection of some types of rights.
For this paper two works are of particular relevance. In the first one, based on a study of 189 countries for the period 1981-2010, Melton (2013) uses random effects models and matching techniques to find that de jure entrenchment of the freedom of association, freedom of expression, and freedom of movement improves their de facto protection, while this is not the case for freedom of religion, press freedom, and the prohibition of torture (entrenchment may actually increase the violation of these rights/freedoms). In the second one, Chilton and Versteeg (2016) focus on the relevance of de jure protection of 6 constitutional rights (the right to form political parties, right to unionize, freedom of association, freedom of religion, freedom of expression, and freedom of movement) for the degree of government repression of these rights, i.e. their de facto equivalents, using matching and postmatching regression analysis, as well as a few other estimation strategies as robustness checks. In their study, including up to 186 countries for the period 1946-2012, they find a robust and statistically significant positive impact of the rights to establish political parties and to unionize on government respect for these rights, while freedom of movement and freedom of expression do not exert such an effect. For the remaining two freedoms included in their study (freedom of religion and freedom of association) the results do not allow for clear conclusions. They interpret these findings as a confirmation of the theoretical suggestion that "organizational" rights establishing organizations, having the means and incentives to protect the given rights, become self-enforcing and are de facto more effective than rights that do not establish such organizations ("individual rights"). Importantly, the discussed empirical studies are also valuable sources of information concerning other than text potential determinants of de facto protection of constitutional rights and freedoms and, in particular, those conditioning the significant effect of the text on practice in this area. Among these other factors, the following are typically included: democracy level (more democratic countries are characterized by less government repression), economic development level (wealthier countries tend to have less repression), population size (larger countries tend to commit more violations), political conflict (engagement in both domestic and international conflicts tends to increase rights violations), robustness of civil society (well-developed civil societies strengthen rights enforcement mechanisms), ethnic 1 3 fractionalization (more heterogeneous societies are more prone to rights violations and have more difficulty in enforcing them).
As already discussed in the theoretical section, the most important factor conditioning the relevance of de jure constitutional rights for their de facto protection is the functioning of an independent judiciary (see e.g. Melton 2013). In particular, this pertains to the constitutional judiciary (in countries, where it exists). Constitutional courts sanction the text of the constitution by way of asserting that a given law-making activity of the state fails to conform to the constitution. The functioning of independent constitutional courts constitutes, therefore, a condition for effective functioning of the constitution itself understood as a set of self-restraints imposed on the state, expressed in the form of credibility-enhancing mechanisms (Feld and Voigt 2003;Voigt et al. 2015). Melton (2013) posits that relatively smaller gaps between de jure and de facto constitutional rules relating to catalogues of rights and freedoms will exist where factual constitutional court independence is high. Simmons (2009) andLupu (2013) also confirm that independent judiciaries constitute mechanisms for enforcing de facto rights. However, more and more often constitutional courts have recently taken on the role of an ultimate legislator, adjusting the content of formal rules to changing social circumstances (Stone-Sweet 2007). In particular, this has been so in situations, when transaction costs connected with law-making activity at the constitutional level were high (Stone-Sweet 2000). On the basis of these arguments, one may conjecture that judicial activism at independent constitutional courts may lead both to an increase, as well as to a decrease, of the gap between de jure and de facto constitutional rules. This is one of the doubts that our empirical study, presented further, will aim to resolve for the case of postsocialist countries.

Post-socialist countries
Transformation of political and economic systems that took place in post-socialist countries of Europe and Asia, beginning in 1989, required establishing new constitutional frameworks and this process has sometimes been called in the literature a "gigantic natural experiment" (Elster 1993). Research on the relevance of constitutional rules for post-socialist transition constitutes part of a broader strand of literature interested in studying the role of formal and informal rules (institutions) in this process (see e.g. Pejovich 1997Pejovich , 1999Pejovich , 2003Winiecki 2004;Gruszewska 2012). Studies in constitutional economics confirm that for post-socialist countries a series of de facto constitutional rules (e.g. concerning the structure of power, bills of rights, and constitutional court independence) have been significant for successful implementation of economic reforms in transition (Metelska-Szaniawska 2009. In particular, if these rules impose constraints on representatives of state power in order to enhance their commitment to promises made by enacting given policies or reforms, such rules contribute to a conducive constitutional setting for the implementation of these policies and reforms. The question remains, whether, and if so, to what extent, de jure constitutional rules have such effect. Bjoernskov (2015) indicates, for example, a ceteris paribus negative direct relationship between de jure property rights protections in post-socialist countries and their economic growth. Other works (e.g. Smithey and Ishiyama 2002;Herron and Randazzo 2003;Metelska-Szaniawska 2016) find an insignificant, and under some conditions negative, direct relationship between de jure constitutional court independence in postsocialist countries in the period 1989-2012 and economic performance. Such findings provide particularly interesting ground for analysis of the relevance of de jure constitutional rules in post-socialist countries for their de facto equivalents drawing on the theoretical and empirical arguments presented earlier in this paper.
Although the specific constitutional solutions adopted by various post-socialist countries vary significantly, the main common feature of these constitutions was the attempt, reflected in their content, to break away from the socialist or communist past, by giving priority to formal provisions declaring the democratic nature and sovereignty of these states (Sadurski 2002). Such circumstances correspond with the view of the constitution's role as a blueprint. 15 In such case the discrepancy between de jure and de facto constitutional rules is initially determined by the informal institutional framework functioning in post-socialist countries/societies at the moment of drafting and enacting de jure rules (cf. Pejovich 1997, Winiecki 2004). In an empirical study for all post-socialist countries for the period 1989-2011 Metelska-Szaniawska (2020) confirmed the presence of two counteracting effects in relation to the evolution of the de jure-de facto constitutional gap (referring to 6 constitutional rights and freedoms) in post-socialist countries: the effect of the aging of constitutions (increase of the gap as time passes from the adoption of a constitution), as well as the constitution-as-blueprint effect, however only for post-socialist countries other than former Soviet republics in Asia, Belarus or Russia. More importantly, this study also identified several explanans of the de jure-de facto constitutional gap relating, in particular, to the democratization process in these countries, presence of political conflicts, as well as their constitutions' age and degree of comprehensiveness. These considerations, however, related to the size of the de jure-de facto constitutional gap (in the area of selected rights and freedoms) and did not ask the question about the significance of de jure protection of these rights for their de facto functioning. They did, nevertheless, indicate that the degree of comprehensiveness of the de jure bill of rights envisaged in a constitution (i.e. the number of included rights and freedoms) was a relevant factor, as promising too much in this respect could lead to an even larger constitutional gap ("the key to successful avoidance of the negative consequences of large de jure-de facto constitutional gaps lies in making sure that countries drafting constitutions which are intended to serve as blueprints 'don't bite off more than they can chew'"-Metelska-Szaniawska 2020, pp. 24-25).
It also seems particularly interesting to determine the role of constitutional judiciaries and, in particular, their independence for the significance (or not) of de jure constitutional provisions for de facto protection of constitutional rights and freedoms in post-socialist countries. As described earlier, judicial activism at independent constitutional courts may lead both to an increase and to a decrease of the gap between formal and factual constitutional rules. The specific role of constitutional courts in post-socialist countries stems from the fact that since virtually the beginning of their existence these courts have been focusing on determining the precise meaning of the content of constitutional rights and freedoms in these countries, having at the same time a relatively strong formal position in their system of powers (Sadurski 2012). The results of empirical studies concerning the role of the degree of (de facto) judicial independence for the size and evolution of the de jure-de facto constitutional gap in post-socialist countries remain so far inconclusive (cf. Metelska-Szaniawska 2020).
One of the most convincing conclusions stemming from the existing crosscountry studies concerning the significance of the constitution text for constitutional practice and economic performance is that this relationship is in part conditional on the political regime (in particular, whether it is democratic or authoritarian) and political stability in the given country (periods of tranquility vs. periods of conflict) (e.g., Melton 2013; Ginsburg and Simpser 2013). With regard to post-socialist countries, Metelska-Szaniawska (2020) provides evidence that progress in democratization taking place in these countries after 1989 went together, ceteris paribus, with mitigating the de jure-de facto constitutional gap (while backlashes in democratization could in part explain the constitutional gap increases in some countries during transition). These results are particularly convincing with regard to civil and political rights. The question remains whether together with the progress in democratization, the content of de jure constitutional rules became, ceteris paribus, more or less significant for the operation of de facto constitutional rules in these countries.
Finally, having just said that the degree of democratization could potentially make for an important factor determining the relevance of de jure constitutional rules for de facto protection of rights and freedoms in post-socialist countries, in this context we should also mention another role for democracy suggested by the literature on the so-called illiberal democracy. States, where fundamental institutions regarding elections are valid but rights are routinely violated, are classified as illiberal democracies (Zakaria 1997). Mukand and Rodrik (2020) argue that for successful transformation, sets of property rights, political rights and civil rights must be respected, what occurs in liberal democracies. Democratic transitions typically do not lead to liberal democracies as they are a "product of a settlement between the elite (who care mostly about property rights) and the majority (who care mostly about political rights)" (Mukand and Rodrik 2020, p. 765). According to such political logic behind the emergence of democracy, minorities have neither the required resources, nor constitute a sufficiently large group in terms of numbers to effectively secure the protection of civil rights. Therefore, electoral, not liberal democracy is the outcome of such political settlement. The investigation of the relevance of de jure constitutional provisions stipulating protection of rights for de facto performance of post-socialist countries of Europe and Asia in this area should be conducted with this context in mind.

Empirical model and methodology
In this section we ask the question whether constitutional de jure civil rights protection in post-socialist states matters for de facto protection of these rights and under what conditions. The main expectation is that by establishing a de jure set of civil rights, post-socialist countries increased the odds for practical execution of these rights. Our study covers the following list of de jure civil rights and their de facto equivalents: freedom of assembly or association (fra), freedom of movement (frm), freedom of religion (frr), habeas corpus (variable name: hc), and prohibition of torture (prt). 16 Aggregate variables rights_de_jure and rights_de_facto are constructed based on average scores on these 5 rights in their de jure and de facto dimensions. With regard to de jure rights, we focus simply on the existence of rules pertaining to the protection of these rights in the constitutions and do not consider their wording in detail due to potential subjectivity of such approach and numerous language nuances that would render our comparative analysis questionable. De facto indicators reflect government practice (violations) of these rights. Our empirical tests involve explaining variation in de facto protection of these rights (both for all rights, as well as for each of them separately) by reference to their de jure equivalents, as well as other potential determinants of rights enforcement.
The selection of control variables, i.e. potential determinants of rights enforcement other than de jure rights provisions, is based on the theoretical and empirical literature surveyed in Sect. 3 and includes: a measure of conflict (variable name: conflict), number of years since the adoption of the given post-socialist constitution (constitution_ time), the political competition component of an indicator of democracy (democracy_ competition), 17 a de facto judicial independence indicator (judicial_independence), log of population (population), log of GDP per capita (GDP_per_capita), and a measure of the robustness of civil society (civil_society). We also include a dummy variable for the group of countries that joined the European Union in 2004 (EU) as the accession process may have contributed to the existence of an external rights-enforcement mechanism in these states during the period covered by our study. 18 16 The selection of rights for the empirical study is determined by the availability of de jure and de facto measures providing for the possibility to match a single de jure right with the respective de facto measure. 17 Given the broad nature of the usual composite indicators of democracy/democratization, which, in fact, often also contain a rights enforcement component, and in order to avoid allegations concerning the likely co-determination of our dependent variable and the variable relating to democratization, we include only the political competition component of the democracy indicator, as provided by Vanhanen (2000Vanhanen ( , 2016, in our model. 18 In earlier tests we included several other variables, however as they turned out insignificant in all (or nearly all) specifications, we removed them from the final analysis presented here. This concerned, in particular, variables aimed at capturing ethnic heterogeneity, dummy variables relating to country groups, e.g. those that constituted independent states prior to the post-socialist transition process, as well as another potential external factor-the ratification of the International Covenant on Civil and Political Rights (however, the majority of post-socialist countries ratified it at the beginning of their transformation or even prior to the transition process). We also studied the potential role of more detailed characteristics of countries' systems of government, in particular the strength of checks and balances and classification of regime types proposed by Cheibub et al. (2010) but they also proved insignificant in nearly all cases so we restrain from presenting these results in the paper.
The descriptive statistics for the dependent variable and the complete set of explanans are summarized in Table 3. We list all variables included in the analyses, together with their descriptions and data sources, in Appendix (Table 9).
Thanks to a relatively stronger electoral enforcement mechanism, democratic regimes with a larger degree of political competition are expected to be more effective at upholding rights declared in the constitution and demonstrate higher constitutional compliance than authoritarian ones. A similar positive effect is also hypothesized for countries which have a well-developed civil society, favorable economic conditions, and a relatively more independent judiciary as a crucial element of the rights enforcement mechanism. On the other hand, countries plagued by armed political conflict (including intra-and interstate wars), with large populations, are expected to be more prone to constitutional violations. We question the significance of the age of constitutions in this context (since its usual effect increasing the de jure-de facto gap is expected to be offset by a counter-effect connected with the post-socialist constitutions' role as blueprints, at least for some countries in the sample). In order to study under what conditions de jure rights provisions matter for their de facto equivalents, we further enrich our model by including interactions of de jure rights variables with variables proxying for potentially relevant conditions. We discuss these specifications in more detail alongside the presented results. We test our model employing panel data regression techniques. Our panel includes 26 out of the 28 existing post-socialist countries and the time period spans from 1989 to 2010 (the upper limit being determined by data availability, however covering the core period of post-socialist transition and the first two, or for some countries nearly two, decades of the functioning of post-socialist constitutions). We frame our analysis in the so-called 'transition time', rather than calendar time, in order to account for the fact that transition started at different times in different countries. 19 Transition time is defined as beginning in 1989 for Poland and Hungary, 1990 for other Central and Southeastern European countries (except Albania), 1991 for Albania and the Baltic states, and 1992 for the former Soviet republics.
Given potential endogeneity problems in our data and the fact that due to lack of appropriate instruments a more sophisticated instrumental variables analysis is not feasible, we consider the fixed-effects model, enabling to control for countryspecific fixed effects, more reliable for drawing conclusions from our panel than the random effects model. 20 At the same time we are aware that the fixed-effects model does not allow to study the effect of time-invariant variables on the dependent variable. Therefore, to expand our perspective, we perform the Hausman-Taylor regressions (Hausman and Taylor 1981;Amemiya and MaCurdy 1981). This approach combines the consistency of fixed-effects estimators with the applicability of the random-effects model and in this way, in particular, allows to estimate the coefficients of time-invariant variables in our model. The individual means of exogenous regressors are taken as instruments for the time-invariant regressors, which are correlated with the individual effects (Baltagi 2001). The key step of the Hausman-Taylor estimation is, therefore, to distinguish between regressors that are uncorrelated and those that are potentially correlated with the errors. Based on the relevant literature surveyed earlier, as well as statistical testing, we identify conflict, constitution_ time, population, and GDP_per_capita as exogenous time-varying variables in our model. The only time-invariant exogenous variable is the EU dummy variable. The remaining variables-democracy_competition, judicial_independence, civil_society, and our crucial variable of interest in this study-rights_de_jure-are considered as endogenous time-varying variables. 21 Interactions between endogenous and exogenous variables are also regarded as endogenous.  Table 4 presents the results for the baseline model aiming to explain the aggregate measure of de facto rights. As a starting point, in Column I we demonstrate the results of ordinary pooled OLS estimation for our panel, Column II reports the results with fixed effects (FE), and Column III-for the Hausman-Taylor (HT) approach. Several interesting conclusions emerge from our analysis. Firstly, many potential explanans, included as control variables in our model, confirm their significant link with the aggregate measure of de facto civil rights protected in post-socialist countries. Such negative significant effect is found in all three columns of Table 4 for presence of an armed conflict (countries experiencing conflict have weaker de facto protection of rights), age of the constitution measured by the number of years since its adoption (a weak link that may be connected with gradual obsolescence of constitutional rules), and population size (large populations are more prone to constitutional violations). Two variables are found to be positively linked to the aggregate measure of de facto civil rights protected in post-socialist countries: GDP per capita 22 and robustness of civil society (indicating, in line with our expectations, that better economic conditions and more developed civil societies are favorable to effective protection of rights). For the remaining control variables the results are mixed or suggest no statistical significance. Most importantly from the point of view of the main interest of this paper, however, the aggregate measure of de jure civil rights protection fails to confirm that post-socialist countries coding more rights in the text of their constitutions also experience stronger de facto protection in this respect. This is demonstrated by the statistically insignificant coefficient on the rights_de_ jure variable in all three columns of Table 4. 23 Before drawing further conclusions from these results we take a deeper look into the potential indirect effects of text on constitutional practice in protecting rights in post-socialist countries.

Results
In Table 5 we present estimation results for specifications which supplement the baseline model with interactions of the de jure rights proxy with subsequent explanans included in the model (each row in the table relates to a distinct specification), again both for FE and HT. Given the so far not convincing results as regards direct effects of constitution text on constitutional practice in the studied context, the inclusion of these interactions allows to study potential indirect effects, i.e. answer the question whether in certain circumstances or under certain conditions de jure rights provisions do significantly matter for their de facto equivalents in post-socialist countries (and in what way).
The results presented in Table 5 demonstrate significant positive effects of de jure rights on their de facto equivalents conditional on judicial independence, democratization (political competition), and robustness of civil society. In line with our expectations concerning the role of various rights enforcement mechanisms, this signifies that if a country is characterized by relatively higher judicial independence and/or more political competition and/or a more developed civil society, the content of the constitution significantly positively impacts de facto protection of rights. At the same time, the interaction with GDP_per_capita in these estimations obtains a significant negative coefficient. In countries enjoying relatively better economic conditions, formal protection of constitutional rights is not a necessary prerequisite for its factual operation but may actually hinder it-in particular, where countries fall in a trap envisaging too broad guarantees of the protection of rights in their constitutions, trying, in other words, to 'bite off more than they can chew ' (cf. Sect. 3.3). Finally, we do not find any evidence of an indirect effect of de jure rights on their de facto equivalents conditional on the presence of conflict in postsocialist countries, their population, the age of constitutions, or EU accession. 24 The results presented in Table 6 allow to take a more detailed look at the relationship between de jure and de facto protection of each type of rights included in our study. 25 They reveal a solid conclusion: Only with regard to freedom of assembly/ association de jure protection in the constitution significantly affects de facto constitutional practice in post-socialist countries and this in the expected positive way, i.e. higher de facto protection of freedom of assembly/association is experienced by countries where this right is more strongly protected by constitutional provisions. Similar evidence is not found for any of the other four rights included in the study. We explain this by referring to the nature of these rights. While we do not study typical "organizational" rights, as classified by Chilton and Versteeg (2016), such as the right to unionize or the right to form political parties, within our sample of rights freedom of assembly/association is clearly the most "organizational" in nature on the "organizational"-"individual" rights spectrum (it is inherent in both freedom of assembly, as well as freedom of association, that as citizens enjoy them, more or less formalized groups/organizations arise, which may strive for further protection of these freedoms). Therefore, in light of Chilton and Versteeg's (2016) argumentation, presented earlier in Sect. 3.1, it is not surprising that only with regard to this right constitutional provisions are found to matter for post-socialist constitutional practice. It is worth noting that R 2 is significantly lower for estimations presented in Table 6 than for the aggregate rights measures, especially for rights other than freedom of assembly/association, suggesting that there exist other explanations of de facto protection of "individual" rights that have not been accounted for in our framework. For example, in the case of freedom of religion this could be the factual distribution of religions in a given society and the role of religious minorities, while in the case of freedom of movement a likely factor could be the development of infrastructure and access to means of transport in different post-socialist countries. We leave the verification of these hypotheses for further studies concentrating on the protection of each of these rights.
One can find some indications of differences between the mechanisms behind de facto protection of the 5 rights included in this study in the results obtained for the control variables in the subsequent columns of Table 6. No single control variable is significant throughout the table. Robustness of civil society (as a positive factor) and the age of the constitution (as a negative one) come close to confirming their significance for all 5 rights included in the study but there are also variables that prove Post-socialist "illiberal democracies": do de jure…   insignificant for all of them (i.e. those that also failed to confirm their significance for the aggregate rights_de_facto measure-democracy_competition and EU_2004).
There are also interesting cases of different roles of the same factor in de facto protection of different rights, e.g. while for freedom of movement, freedom of religion and prohibition of torture more populated countries experience lower de facto protection, for habeas corpus the relationship is reversed (a contrary pattern is identified with regard to freedom of religion and habeas corpus for GDP_per_capita). These are subsequent open questions for future research on the determinants of de facto rights. Concentrating further on the main focus of the paper, i.e. the role of de jure protection of rights for their de facto equivalents, given the results obtained above with regard to freedom of assembly/association, in the final part of our empirical study we check for the existence of conditional effects for the dependent variable fra_de_facto by including interactions of fra_de_jure with the remaining explanatory variables in our model. The results of these estimations are reported in Table 7, which follows the convention of Table 5 presented earlier for the aggregate measure of rights. They demonstrate that in circumstances of relatively stronger conflict, as well as in countries enjoying higher judicial independence (according to the more reliable HT estimations), envisaging de jure protection of freedom of assembly/association in a country's constitution contributes to de facto protection of this freedom. The same is true for countries performing better economically, while for states with larger populations there is evidence suggesting that de jure protection of freedom of assembly/association may serve as window dressing.
All in all, the results obtained in search for determinants of de facto protection of civil rights in post-socialist countries do not confirm, in a convincing way, the role of their de jure equivalents, contradicting our general expectations in this respect. However, they can be treated as an extension of the conclusions formulated earlier in the literature with regard to the factors responsible for the enforcement of civil rights in post-socialist countries, as well as a step towards a complete and complex empirical account of the constitutional credibility problem resulting in emergence of such phenomena as a the de jure-de facto constitutional gap or constitutional underperformance in these countries.

Conclusions
The aim of this paper was to contribute to a better understanding of the role of de jure constitutional rules for their de facto equivalents, with particular emphasis on protection of rights and freedoms. In this way we also intended to indirectly enrich the state of art concerning economic effects of constitutions, as such effects have repeatedly been confirmed in existing literature for de facto constitutional rules, while these studies failed to make the link to de jure constitutional text or brought questionable conclusions in this respect.
By linking institutional and constitutional economics literature with currently developing studies on illiberal democracies, enforcement of rights, constitutional underperformance and constitutional de jure-de facto gap, we provided a theoretical framework allowing for a more systematic account of the central issue of the paper. The empirical study, based on the unique setting of post-socialist countries, revealed that the content of de jure constitutional rules originating from the text of these countries' constitutions had, generally, no significant impact on their de facto performance in the area of protection of rights and freedoms. Exceptions from this general finding may only be expected in the area of "organizational" rights, for which mechanisms of selfenforcement are at play (e.g. freedom of assembly/association). In principle, therefore, countries striving to improve factual protection of rights should not limit their efforts to envisaging broad de jure protections of rights in their constitutions but also guarantee the functioning of a highly independent judiciary, a competitive electoral democracy, and a robust civil society. Only under such conditions does the constitution text matter.
